Two half-brothers convicted of killing a 19-month-old girl in an "evil" revenge arson attack have been jailed.

Siariah Letang was overcome by smoke in the blaze in Camberwell, south London, in September, the Old Bailey heard.

Richard Kwakye, 28, of Twickenham, south-west London, was jailed for life with a minimum term of 35 years for murder and attempted murder.

Dimitri John-Lewis, 19, from Paddington, was jailed for 12 years for manslaughter and perverting justice.

Their mother Josephine Nicholas, 46, of Paddington, was jailed for four years for perverting justice by giving police false information.

Judge Giles Forrester said the offences were "despicable and evil".

'Terrified screams'

The baby girl died of carbon monoxide poisoning after Kwakye started the fire in the early hours of the morning, by pouring petrol, supplied by his half-brother John-Lewis, through a letterbox and lighting it.
